PHOTOS: 8 arrested, 5 sought after heroin ring bust

Authorities say a two-year investigation into a southern Delaware drug distribution ring has netted charges against 13 people and the seizure of roughly three pounds of heroin.

Officials said Tuesday that more than a dozen law enforcement agencies were involved in the investigation.

Authorities allege that 31-year-old Deangelo McGlotten of Felton was the ring leader of the drug distribution network, and that the illegal proceeds were being laundered by 37-year-old Salman Choudhary of Georgetown through casinos, businesses, and personal properties.

Officials say the suspects are charged with 77 separate criminal offenses, and that the investigation resulted in the seizure of heroin valued at more than $1 million.

Also seized were 23 cars and a number of rifles and handguns.

"Heroin is a serious, serious problem in Delaware right now and all of law enforcement is working together to combat it," said Attorney General Matt Denn in a statement. "This operation puts a significant dent in the heroin traffic in the southern part of the state."

Eight suspects have been arrested, while five more are still being sought by police.
